Specification of Letters Patent.

Application filed April 15, 1913.

Patented Mar. 724, 1914i. Serial No. 761.383.

1 b all whom it may concern.

to it known that I, EZRA C. BROGKWAY, a citizen of the United States,residing at Trenton, in the county of Mercer and State of New Jersey,have invented certain new and useful Improvements in Clock-Banks; and Ido hereby declare the following to be a tall, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to coin controlled winding mechanism for clocksand the like, and as its principal object contemplates the provision ofa winding mechanism so constructed that the time piece can not berewound except by the introduction of a coin.

A turthcr object is to construct the device in such manner that afterthe introduction or the coin and the subsequent winding oi the clock,the withdrawal of the winding key will etif'ect the delivery of the coininto a till or coin receiver arranged within the casing of the clock.

It still further object of this invention is to construct the windingmechanism with such regard to proportion number and arrangement of partsthat it may be cheaply manufactured, readily applied to any clock ortime piece of standard construction, and will be durable and etiicientin its operation.

The above and additional objects are accomplished by such means as areillustrated in the accompanying drawings, described in the followingspecification, and then more particularly pointed out in the claim whichis appended hereto and forms a part of this application.

with reference to the drawings, wherein I have illustrated the preferredembodiment of my invention as it is reduced to practice, and throughoutthe several views of which similar reference numerals designatecorresponding parts: Figure 1 is a rear elevation of a clock equippedwith this invention, illustrating several of the various parts in brokenaway section to clearly disclose the interior arrangement of themechanism. Fig. 2 is a section on the line 22 of Fig. 1. Fig. 3 is adetail view of the device employed in preventing the withdrawal of thecoin from the box after it has been inserted. Fig. a is a section on theline t-at of Fig. 1; and Fig. 5 is a detail view of the coin cup.

Proceeding now to the description of the drawings, the numeral 1designates the clock casing, the rear wall of which is provided. as 2,with an elongated horizontally ex tending coin slot, the middle portionof which is enlarged to produce a circular open mg 3, adapted to permitthe insertion of the shank -.t of the winding kev 53. This w nding key 5dillcrs from the ordinarv winding key employed in time pieces in thisrespect, that the terminal of the shank -i is biiurcatcd to produce thefork tines 6, the inner faces of which are spaced apart a dis tanceslightly less than the thickness of a dime, which is the coin preterablvemnlovcd in this mechanism. It will be i'cadily hpparent that by thisarrangement of the tines (l, the resiliency of the metal of which themember 5 is constructed will act to grip the coin in the desiredposition. 4

In order to permit the application of the coin to the main spring stemT, there has been provided a cup-shaped member 8 which may be formedintegrally with or secured to the member '7 in any desired manner. Thiscup member 8, the mouth of which opposes the rear wall 9 of the clock,is provided interiorly with a plurality oi laterally GX tending inwardlydirected tongues 10 which are formed integrally with the nun'ibcr S andare substantially V-shaped. The tongues 10 are arranged in the nature ofratchets with the corresponding edges similarly inclined so that theinserted coin may not be rotated to turn the main spring abnormally. Inthis connection it will be readily observed that it the main spring isturned positively the coin will engage the straight edges of the members10 and rotate the stem 7 in a normal direction, but if an attempt ismade to rotate the stem abnormally the coin will slide over the inclinededges of the tongues. It will be observed that by placing the coinbetween the tines 6 of the key and inserting it through the slot 2, thatthe coin will be projected into the cup 8 and will engage the straightedges of the tongues 10. To wind the clock it then remains only to turnthe key 5 in the usual manner.

Since the principal object of this invention is to prevent thewithdrawal of the coin after the winding of the main spring, it isnecessary to provide some automatic means for engaging the coin andett'ecting its delivery into the till or receiving chamber, as

indicated at 11 in Fig. 1. fore, been provided in this invention ahinged plate 12- mounted interiorly of the clock casing and on the rearwall 9 thereof. T he plate 12 is bifurcated, as illustrated in Fig. 3,to produce the yoke arms 13 andis disposed on the wall 9 so that theyoke arms in normal position lie one on each side of the opening 3 andextend across the slot 2. From the foregoing it will be noted that asthe coin is inserted the plate 12 will be swung upwardly on its hingeuntil the coin has reached the cup 8, at which time the rotation of thekey 5 will tend to bring the coin in a verticalposition, thus bringingthe arms 13 on each side of the coin, and permitting the plate 12 toswing downwardly into its normal position. After the completion of thewinding operation, the key is withdrawn in the usual manner, but thecoin is held against-- withdrawal by the plate 1:2, as will be readilyapparent by reference to the drawing. As the tines (3 issuefrom theopening 3 they will of course withdraw from the coin, which will thendrop into the till or receiver 11.

The actual construction and operation of this device being thusdisclosed, it now re mains to emphasize the fact that the simplicity ofthe construction and arrangement of the various parts of this inventionis regarded as the essential feature of the device.

In reduction to practice I have found that the form of myinvention,illustrated in the drawings and referred to in the abovedescription, as the preferred embodiment is the most eflicient andpractical; yet realizing that the conditions concurrent with the l herehas, thereadoption of my device will necessarily vary, I desire toemphasize the fact that various minor changes in details ofconstruction, proportion and arrangement of parts may be resorted to,when required, without sacrificing any of the advantages of myinvention, as defined in the appended claim.

What is claimed is:

A clock bank including a clock casing,

,a clock mechanism arranged therein, a coin cup carried by the mainspring stem, said cupbeing pro ided interiorly with diametricallyextending coin grooves, an elongated horizontally extending coin slotformed in the rear wall of said clock casing and in alinement with themain spring stem a singed plate mounted interiorly of said casing and onthe rear wall thereof, yoke arms formed on said plate and normallydisposed to extend across the said coin slot, said rear wall of saidcasing being provided approximately midway the length of the said coinslot with a central opening adapted to receive a winding key saidopening being formed in registration with the space between the saidyoke arms, a winding key, pair of spring tines formed terminally of thesaid winding key and adapted to hold a coin, said hing-ed plate beingadapted to permit the insertion of the coin and key and to permit thewithdrawal of said key but being further adapted to prevent thewithdrawal of said coin.

In testimony whereof I affix my signature in presence of two witnesses.
